This brings me back. In the late '90's, I interned at Sun Microsystems with the team responsible for the ISDN infrastructure that enabled people to work from home. My job was to automate modem SW upgrades for modems in racks in data centers and for remote users. The latter group was more challenging to serve since the upgrade could only run when they were connected and and "breaking" something killed their internet connection - it happened a couple times :(
